我如何写这个要求作为一个es6导入语句 [英] How do i write this require as an es6 import statement

问题描述

问题

我有这个需求声明

  require 'smoothscroll-填充工具'）填充工具（）; 
  

但是我想把它写成一个es6 import语句

我尝试过

  import'smoothscroll-polyfill'; 
  

和

  import * as'smoothscrollPolyfill'from'smoothscroll-polyfill'; 
  

但是无法使其正常工作，那么导入包的方法是什么？

解决方案

您可以分两部分进行，首先是导入，然后调用函数：

$ b $从'smoothscroll-polyfill'导入smoothScrollPolyFill; b

  
 const polyfill = smoothScrollPolyFill.polyfill（）; 
  

假设它是默认导出。如果它是一个命名导出，它将是：

  import'smoothscrollPolyFill'from'smoothscroll-polyfill'; 
 const polyfill = smoothScrollPolyFill.polyfill（）; 
  

另外，如果 polyfill 本身是一个命名导出和，它不在乎什么这个是在调用时：

<$ p $来自'smoothscroll-polyfill'的p> import {polyfill};
polyfill（）;


...但再次注意假设。

Problem

I have this require statement

require('smoothscroll-polyfill').polyfill();

But I would like to write it as an es6 import statement

I have tried

import 'smoothscroll-polyfill';

and

import * as 'smoothscrollPolyfill' from 'smoothscroll-polyfill';

But cant get it to work correctly, so what is the correct way to import a package like this?

解决方案

You'd do it in two parts, first the import, then the function call:

import smoothScrollPolyFill from 'smoothscroll-polyfill';
const polyfill = smoothScrollPolyFill.polyfill();

That assumes it's the default export. If it's a named export, it would be:

import {smoothScrollPolyFill} from 'smoothscroll-polyfill';
const polyfill = smoothScrollPolyFill.polyfill();

Alternately, if polyfill itself is a named export and it doesn't care what this is when it's called:

import {polyfill} from 'smoothscroll-polyfill';
polyfill();

...but again note the assumptions.
